How do you usually deal with stress or tough situations?

I strongly agree with @funshomoses; you can’t rule out stress in your life completely. Yes, you can avoid it. First, you need to identify what actually causes stress in your life, such as a friend, family member, significant other, job, living conditions, or finances. Once you realize what the issue is, you have to find ways and things to relieve stress. Having a mentor or a therapist works. But it’s all about developing beneficial habits and losing those bad habits that create their stresses in your life. I remove anything negative in my life. I remove anything that adds stress to my life, no matter what or who it is. I’ve been doing it for so long; it’s like an exercise. This has become a natural instinct for me. Just learning to let go and not please others is one of the hardest things for people but always causes a lot of stress. Unfortunately, many things in life require you to learn to let go of something or please others to a certain extent. Know your worth, let go of purposeless jobs, get a better one, and stop pleasing others; your friend or family member’s opinion does not justify your stress. Keep positive things and positive people around you. Nobody’s perfect, so only speak positively.

Stress management is very paramount as human being however,  you cannot totally rule out stress form your life but you can avoid it .

Dealing with stress is about  you being able to control how you handle it.  Avoid factors that are Stressors in nature.
