Of course you can do it.
Of course, you’re scared it won’t be as good as you want it to be, and chances are very good that, yes, it won’t be.
So what? An imperfect-but-realized dream is better than the perfect project that remains in your imagination forever. An imperfect-but-finished-and-shipped project is better than no project in sight.
So sit down, make your thing, and get it out there. Yes, make it as good as you possibly can in the time you allocate, but get it out there, knowing that perfect is always the ideal but it won’t be perfect.
Give yourself permission to release a great product that is not perfect, and then go and make it as great as you can.
You can do it. That’s settled.
Now go do it!
