The next level of thought processing after being able to get rid of negative thoughts and doing positive things which includes letting go of resentment against annoying people who you blocked on Facebook and unblocking them again without feeling too much hassle underneath, is developing a stronger mind.
The art of developing a stronger mind goes hand in hand with the principle of dropping all grudges and moving on with your life while letting go of something that just bugged you so much. It's pretty much dropping the things that just seem to hold you back personally. Trust me, it's not really personal when you made a personal decision about someone else; the person had to really do something to get you to that state of mindful decision. I'm talking about the personal decision of the person underneath the actual you- if you were to examine yourself throughout the day, you would get some feelings of wanting to steer off course every once in awhile such as wanting to be a little lazy or just feeling worn out.
There are just those positive priorities that just stand out in you, if you were to take the time to just notice them and stop aimlessly doing some unproductive things even if you want to take it from a literary context and say that it provides you some beneficial relief and gives you something to do. Maybe it just hasn't really been developed in some people yet, or maybe just some people are feeling really distraught or bothered and just seems like no matter what a person would say or even if the whole world was to present it in a plain context, they would just still not feel right about something.
I guess developing a stronger mind, means remembering all the reasons that helped you find resolve about something you didn't enjoy dealing with in the past. It also means letting go of that quickie such as turning on that cute television show or cute card game Microsoft provides and getting some personal tasks that just highlight your life out of the way before engaging in some fun time. Maybe fun time could also be learned to be something that's a part of you.
