What's your secret for staying motivated and not feeling discouraged?

Usually working on different things to keep me entertained!

Discipline, I am motivated less than 20 minutes a day. People are usually discouraged because they seek comfort zone. Mental techniques like paradoxal intention and actor perspective are efficient because they point person in opposite direction, trying to find and work on hard problems without any expectation (for reward).

Keep track of your progress constantly and always be surrounded with like minded people

I think the secret is that discouragement visits us quite frequently, we can only stand up if there is any urgency in our lives.

ignore negativity!
