Clarity is essential. Knowing exactly what you want builds your self-confidence immeasurably.

Deal first with whatever is causing you the greatest emotional distress. Often this will break the logjam in your work and free you up mentally to complete (the) other tasks.

Focus very clearly on a few small things. The purpose of a business is to give someone something that they want. Have a product or service that's really excellent. [...] What can you offer that no one else can offer and will satisfy them at a higher level than what anyone else can?

Practice the philosophy of continuous improvement. Get a little bit better every single day.

Remind yourself that problems come not to obstruct, but to instruct.

The act of taking the first step is what separates the winners from the losers.

Single-minded concentration in the direction of your dreams intensifies your desires and increases your self-confidence.
