As great as it is to think, study, analyze, and philosophize there is a time where we need to turn-off our brain and just do.
I am suggesting a detached, low pulse, low heatbeat approach to executing tasks. Use as little brain activity as possible to begin executing a difficult activity. This is very much different from the typical "gung-ho" approach we see from self help. There's no need to hype yourself up to do something. You'll burn out trying to amp yourself up for every activity and face will-power fatigue. By purposefully turning off your brain and executing something immediately, you do not give your brain enough time to rationalize not doing something challenging.
- Heavy weight you're afraid of? Think nothing of it, begin the set. Only after you pick up the weight you have all systems firing. (Not saying be a dumbass with floppy form)
- Don't want to run? Don't spend a second on how much it might suck, don't even amp yourself up. Put your shoes on and go.
- Cold shower? Don't tense up, get hyped. Step into the cold like it's just another shower.
- Hot girl you want to approach? Approach right away. Don't even let your heartbeat quicken, don't worry about what to say, you'll figure it out. Execute faster than your brain can give you anxiety.
- Don't want to study? Think nothing of the challenge, just open your book and begin.
Thinking about a challenge does not solve it. It just magnifies the challenge in the mind, making it more difficult to overcome. Beyond just the minimum level of strategizing, additional analysis often becomes a hindrance.
Further, by executing on tasks immediately, without thinking of the challenging, without over-analysis, we can reduce will-power fatigue. You use much less will-power trying to study when you do it immediately and use much more when you spend an hour thinking about it and procrastinating.
If you're struggling with overthinking and executing on difficult tasks, practice turning off your mind and just doing. If you're having approach anxiety, practice turning off your brain and executing in other areas of your life until it becomes second nature. Works best when you practice executing tasks that you fear - at least just a little bit and work your way up to bigger challenges.
