"Hold yourself responsible for a higher standard than anybody else expects of you. Never excuse yourself." 

Henry Ward Beecher

Don't blame your mistakes on anyone else, but yourself, and don't look for an easy way out of everything. Challenge yourself. Prove your competitors and critics wrong, do the unthinkable, go above and beyond. Leave a mark and people will make legacy, so don't sell yourself short, and when you do something bad own up to it. Work hard on your achievements and avoid mistakes. Aspire to be something great, and work towards it. Aim high, but have low expectations. Be something, you'd want others to follow.
