Have you ever had an idea and you were so thrilled about it? For few hours, maybe days you were dreaming or possibly already did something to make your idea come to life? Then someone or something came and ruined everything?
You said to yourself, it's just not time yet or the idea wasn't good enough. Let me tell you something. It is enough, it is good, actually it's great and it's yours. First overthinking came and effects were fear and self-doubt.
We are all so different, we are all so special. Stop thinking that your ideas are rubbish. Some of them might not succed, that's true, but you have to start somewhere - Rome wasn't built in a day. As individuals we have so much to give. I know, there are many inventions out there and ideas, but yours are special in different, unique way. In your own way.
You might also have interests, that are not the same as others have. That's great! Mine for example vary, from vampires and witches to mind and intuition, to getting successful and also having family, to be a photographer (without even having my camera yet) ect. I'm sure if I ask you what your interests are, you'll find at least three. Embrace them and then you'll get some crazy ideas that can be accomplished.
So we mentioned first two parts of the story, then there is your free time and your job, possibly dream job. You can do anything you want in any part of your life and get paid for it - very well actually. Just don't stop trying, don't overthink and everything can happen, everything is possible.
