Take action.
Don't think.
Don't worry about the right time or the right product or the right idea or the right words.
Make something in the real world, even if it's shit.
These are the things that make a difference. These are the things that do the work when the work needs done.
In the end, all that matters is what gets done, and so, just do something - anything.
Anything productive or useful that is... these are the things.
