I have decided that life is all about what you're doing at the moment and who you are in that moment. In the course of a day you are a son, father, husband, a Boss, an employee or any number of things. You are different things to different people. However, the most important thing is who you really are in your head, because how you feel determines how you will treat others. Feel like shit and shit might hit the fan in the wrong circumstances. I have had episodes I'd rather not talk about, where I did things I shouldn't have just because I was in the wrong headspace.
No one cares about your demons but you. In fact, you shouldn't care about them either, lest you keep feeding them with your baggage. The most important thing I have learnt lately is that you can plan as far ahead as you want but don't focus on anything more than what is within your control for now. That will give you a little more sanity and make you more pleasant to those around you.
All I can hope for in the new year ahead is that I live in the present and make the best of it because as short as life is, it can also feel awfully long if you think too much about things beyond your control. Don't put that kind of pressure on yourself. Just wake up everyday and take it as it comes. I've got no other resolutions other than that, although losing a bit of weight might be beneficial to my health.
