I believe that having self-awareness, and self-discipline, along with patience, positivity, and a hard working attitude is the way to go with being a successful person.
I think this just means doing things that would make yourself happy without having much regrets because the results aren't really going to be that bothersome. This is why being positive and having this mentality to keep on improving is important. It's all about continuing to make adjustments to be successful at doing what you love.
Practicing on maintaining this calm and positive spirit underneath really does help out a lot to not stay stressed about things.
