“When I get sad, I stop being sad and be AWESOME instead. True story.”
– Barney Stinson (played by Neil Patrick Harris), How I Met Your Mother
I think that this is an incredibly inspirational line. While it seems kind of silly to take advice from a television show, I think it makes an excellent point: it is the times when you are at your lowest that you must put in your absolute best. Energy spent being worried and sad can and should be reallocated to taking action and facing the very things that are bringing you down.
And really, all else being equal, being awesome is much more, well, awesome than being sad.
