Just because you have a positive mindset doesn't mean life is all roses. Right now my life could be pretty low. My wife will leave me (or I her - thats yet to be decided), work is trying to find ways to get rid of me due to me being trans and the tbh the distraction of transition. Money is pretty tight, and my children are struggling to come to terms with it all. Nine months ago I was a hair away from suicide, and SRS is something that isn't covered by insurance or even available in New Zealand. These are pretty big issues, but I still call them opportunities. All that could easily point to "my life is terrible"
BUT, they can also be looked at in another way. My wife leaving gives us both an opportunity to live happier lives, I need to up my game at work so the pressure only makes it easier to improve, money will improve with time, I just have to be patient, suicidal impulses pushed me to transition which got me out of a pit of misery, SRS is available in other countries and after we sell the house I can make it happen.
I could go on. I'm too tall, I 'only' managed to grow c cup breasts so far (small on six foot two), my waist isn't really narrow enough, I have a receded hairline and quite thin hair, oh yeah, its taking a long time to get rid of facial hair. Some of those I can't change, some I can. BUT, why would I find a problem for every solution when I can do the opposite?
Life isn't perfect, I don't want it to be. That would be boring. Its a waste of opportunity however to wallow in the negative. Years and years ago when I was super depressed I ran into an interesting concept in a self help book of all things. In a nutshell it said;
The past is the past learn from it
The future isn't set, dream about it
Live in the moment and be present.
Because if you focus on right now, and what you can do in this moment keeping in mind previous 'mistakes' and have a vision of the future you want it can come true. The only person who has the power to really change your life is... you. You can choose the status quo (easy) or you can choose the painful reality that change comes from inside and it has a price. often a high one. I for one am willing to face the pain, pay the price, and make my life better.
Call that setting up for failure (there there will be plenty more) some might choose to call it over reaching (entirely possible!) I call it a life worth living.
