To start of, i hope i am not going to sound arrogant in this response, this is not my intention.
I can relate very much to what you're saying. I've felt like that for most of my life.
But i got out of it. Because i found out who i want to be, and all i do, works towards that. Every second of every single day.
I don't think i am particularly smart, or, 'capable'. What i do know is what i want, and that for me, it's either that, or death. And death is not that appealing to me anymore. For example, i just got a new job. I'm now cleaning at a four star hotel. Repetitive, high pressure, and it's hard work. But i love it. Because i am working towards something, and i know that what i do learn here, everything i learn there, is something i can use to achieve that goal i have. And i'm paid more than at my previous job.
So my advice to you, would be, don't strive to get as much money as possible so that you might be able to travel later on. Start traveling now. Right here, right now. Find out what you need, and get it. It's easier said than done, i know that. But would you rather be a prisoner?
