Have you ever done it? It's amazing the effect of taking a shower, putting on a nice perfume, some casual but nice clothes ( pants not shorts ) just to stay at home. Funny thing is, when I don't feel like going out to do something and I plan to postpone, if I get myself nicely dressed, I will naturally get the will to just go out and solve shit since I am already looking good.
