Seeing all my saved loved ones and friends: my Dad, grandparents, other relatives, best friend, other friends that have passed on; earthbound loved ones and friends; RR friends; and tons of new friends. And my favorite pets from earth. And even angels!
Joy! Laughter! Love! Excitement! Fulfillment! Satisfaction! Peace! No more sad, painful, bad, anxious, scared, worried or uncomfortable feelings or mental or emotional distress of any kind.
Eternally perfect health, flawless beauty, strength, energy and perfect weight. Perfect eyesight. Perfect hair, teeth and nails. No pain, sickness, germs or cavities. No fear of harm to loved ones or self. No fear of even accidentally hurting someone else.
To be a homeowner again -- but a mansion this time with: (1) lovely, tasteful decor, (2) a view, (3) near some kind of body of water, (4) neighboring houses close enough to see so as not to feel alone, but not so close as to feel crowded, (5) with no worries about things breaking, fire, flood, earthquakes, weather damage, termites, wood rot, mice, thieves, etc., (6) filled with beautiful furniture and appliances, a piano, etc., as well as my favorite possessions from earth, (7) great visiting/entertainment/party areas, (8) a spacious, well-lit art studio and similar hobby room with endless, high-quality machines, tools and supplies there or readily available, and (9) a well-equipped/supplied work shed for woodworking and other big projects. (
P.S. My house will be at least partially self-cleaning. Or maybe I will have a robot maid. 
)
A beautiful garden with perfect soil and perfect irrigation conditions; beautiful, fragrant flowers and ornamental trees/plants; a whole bunch of fruit trees/vines/edibles; no weeds, garden pests or plant diseases. A lawn that grows exactly 2-inches tall and never needs mowing.
(Or maybe I will have a robot gardener, too. 
)
A wide, wonderful variety of animals nearby, either as pets or that hang around sometimes (even big ones that let you ride them). Every animal will be gentle and completely tame. And they will all know not to eat the garden plants!
No bothersome flies, mosquitoes, wasps, roaches, gnats, etc.
Beautiful music and other sounds. Beautiful sights. Beautiful smells. Wonderful foods and beverages. Wonderful textures and feelings. No ugly noises. No ugly sights. No repugnant smells. Nothing that tastes bad. Nothing that feels bad.
Beautiful formal and informal clothes and accessories from various times and cultures throughout history. Fabrics that feel wonderfully soft, smooth or just plain pleasant. And a huge closet!
Greatly increased brain power, talent and physical abilities.
Unlimited educational or visiting opportunities with incredible teachers, masters, experts, famous or just interesting people of: the Bible, history, art, music, literature, drama, dance, evangelism, science, medicine, other cultures, etc.
Plenty of fun activities, places to go, fellowship, parties, picnics, celebrations and a wide variety of clubs and groups to join.
No bills or taxes. No need for passports, visas, licenses, permits or legal miscellanea. No fear of accidents, tickets, lawsuits, fees, fines or penalties.
A beautiful new car(s) (if there are cars in heaven

) that doesn't need gas to run, won't ever break down or get flat tires and that will always have that wonderful new-car smell.
Computers and other technology that is easy to understand, won't break down, freeze up, get viruses, get hacked, be misused or run out of power.
Entertainment that is pure, God-honoring and delightful, fascinating, dramatic, touching or funny, etc., or a combination thereof.
Unlimited exploration of every kind! And, especially since so many people have mentioned the possibility of it over the years, flying and movement at the speed of thought!
1 Cor 2:9 But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
Ps 16:11 You have made known to me the path of life; you will fill me with joy in your presence, with eternal pleasures at your right hand.
