Sometimes we complain without realizing we are doing so. It can be something as simple as commenting on the weather conditions outside to a passerby.
As challenging as it may be to process, you chose the life that you have right now, directly or indirectly. It’s easy to blame others for your problems. Unfortunately, that doesn’t solve the problem.
Where you are today is a direct result of a decision you have or have not made. If you are unwilling to change, then there is no need to complain. In other words, stop criticizing your circumstances and change your conditions.
