适者生存

I think if you have to fight all the time, then you may be in the wrong place (e.g. location, company, online forum) or with wrong people

Maturity can make life a bit easier by i.e. picking your battles, negotiating, etc.

Be brutally honest with yourself about what you want from life, find a right place, surround youself with right people, be ready to work for what you want
