Life does not have to be such difficult. If you let some old habits to go, your life will be smooth again.
These are top tips for mental health and inner balance:
Need to be right
People work hard to try to be right. However, anything other than good exercise is futility and frustration. Take some steps backwards and have a look at the situation in a less egotistical, calmer manner. In that way, you can see and
react a bit differently. Has being right accomplished you anything? Does it give you respect or just breeds resentment? Give up burning need of being always right. In that way, you free yourself and others. Start engaging in productive and useful things in life.
Being Perfect
You should note that being excellent does not imply that you are perfect. Many times you need a lot from yourself. You strive to be perfect because you believe in that way you will shut criticism. You should do some work on your self-acceptance. According to a renowned psychotherapist, never waste your time trying to be perfect. Finish your task in a more useful and effective manner than trying in futile to be perfect. Do your best and move on. Do it at your best and with time it will get better in a progressive, natural, and balanced manner.
Start doing
“Just Do It” is an amazing slogan. If you have such attitude, you are guaranteed positive results. Your attitude achieves mental balance. Whenever you set yourself to try, you fail. You did not try to read this article; you did it. 
You did not try to take breakfast; you just did it. You will have excuses when you merely try. Stop lying and making excuses to yourself. You should be honest. You either do it or you don’t. Set your goals and start to achieve them. This will allow you to grow and move forward.
Let go of mistakes
You can learn from your mistakes and learn from your successes too. Then you need to move on. Every experience you have has some lesson. Even the experience you do not get right. Mistakes are there, and you need to learn from them. In psychology, they are known as “successive approximations.”
Let the past go
The past has a myriad of reasons – to inform and instruct. However, you should not live in your past. When you live in the past, it robs you all you have.
