It's fine to wait for an appropriate time, but it's inappropriate to wait forever.
Meeting expectations is good. Exceeding expectations is better.
Don't wait. Tomorrow may be too late to do the things you can today.
Are you moving forward, or just moving?
How can you learn more? By admiring what you've done right? Or by studying what you've done wrong?
Always do what you can do instead of worrying about what you can't.
