Evangelist, First off, you are not a failure! Every one of us who may still have goals to achieve, and haven't reached those goals yet; they are not failures! You either. You are putting too much pressure on yourself.
Second, you may just have to lower your expectations as you begin. I don't know what "market" you are looking at, but many, many people are in the same boat and trying to find their ideal job. Most of us started out with just a job and the experiences you get allows you to move up. My son-in-law got his MBA a couple of years ago. He is gradually working his way up to the type of job he wants. Each step he gets experience to qualify for a better position and his salary is improving with that climb. It's a process...His degree helped with that climb, but he had to work to achieve his goals. He, too, has a lot of student loans. But none of this came in a instruction book on how to obtain a job he so he could just "play". It came with hard work, starting lower than expected, and climbing up the ladder as he worked-and he's worked hard and long hours.
I'm a bit curious, how have these new age teachings in these books influenced you? Are you saying these books give you the knowledge to achieve those goals you want and it hurts you because you want to use them to obtain your goals and shouldn't?
Reading and putting into practice are two different things. Books are wonderful, but they won't give you what you want. God blesses us with so much, but I don't think He promises to give us a dream job. He promises to take care of us. That's what's important. Focus on thanking Him for what you have, not on what He will give you. You might find that will help a great deal.
I don't think you want a job obtained with the influence of the new age and their methods. It won't be a good choice. It's big time
Deception
....What God has given you is the ability to discern, even at a young age, and its a blessing to even realize that these books contained new age practices. The Holy Spirit gives us that decernment so we stay away from this false religion, cults, evil practice and doctrine. I've read quite a few books on the new age, and it is sneaky.
I think the only book you need is The Bible. I know you are looking for a guide to life and to help you secure the job you want and need and to have a good relationship. With God's help you can reach goals, but let me just say experience is the key.
I don't know how old you are-young people waiting for His return maybe feeling they need to acheive their goals before He comes for us. God's timetable will be perfect and He tells us he wants us to "occupy till He comes". Do what you can to achieve your goals with HIS blessings.
Rather than rely on those other books why not pray instead. Pray that God will send you to the right job for you and will help you meet someone who will be a wonderful mate to you. (And, remember do not be unequally yoked with an unbeliever). You may just find both in the same place.
