Lets try something a little bit different
Its really hard to stay in a happy state, whilst also having the emotional / physical energy to be social, be productive, get the girl etc.
I've heard from quite a few people now an interesting concept: setting your life on an upward spiral. Great read here, a summary of a good book here, and a more systems-oriented piece here.
An upward spiral is about continuously re-enforcing patterns, thoughts and emotions which are beneficial and help us grow. Whilst being a very agreeable concept, the challenge is bringing positivity to every facet of your present living, rather than keeping a balance or simply relying on blind optimism.
How am I going to do it? I'm going to go out and spend meaningful time with friends and family. I'm going to work towards tangible Things That Matter in my spare hours (fitness, exploring the world, persuit of love & happiness) and try and exclude a lot of my hobbies which, for the time being, are simply distractions.
