Don't know what I want in life?

Go for it. You lack motivation it seems. Set your mind on something and just go for it. If you want to be a commercial pilot, you'll find a way to pay your lessons. It'll be worth while to you. The whole "loner" jobs .. What do you mean by that? Not all jobs require social interaction if that's what you mean. If the jobs that have presented themselves to you seem like "loner" jobs, you should look passed that. These jobs could give you a lot of experience.
