I remember having a bunch of discussions with my irl best friend about our perception of life itself.
Basically, we discussed that, needless to say, we only have one life to live. Why waste that on only being negative all the time? It was more impressive coming from him considering his circumstances in life that are more than worth being negative about, but yet he still keeps his head above the clouds, because that's all he can do from day to day and hope things work out.
Perhaps it's delusional, but it's also inspirational from him and it shows his strength that no matter what unfortunate circumstance befalls him, he's able to put on a straight face and overcome whatever obstacles appears in his way.
This is why, in part, I've tried to dedicate myself in ridding my own negative thoughts as much as possible. It's an extremely uphill battle, but I don't want to look back and feel like I've wasted my time with negativity. I want to inspire people, to do good things for others, things like that. And I'm not going to achieve that if I just sit and sulk about myself or my life all the time.
