There is no right way, only the way that works for you.
There is no "right way" to do things. Everyone is different. What works for him/her may not work for you. Just because mom does it that way, and taught you to do it this way, doesn't make it "right." It may be the most efficient way for her, or for most people, but if you don't enjoy the process then customize it so that you do enjoy it.
I used to do what I think I should do, as opposed to what works for my needs. With this paradigm, one is limited only to certain actions. It constrains creativity , resourcefulness, and self-expression. Plus, a person may continue doing what they think is "right" and not get the results they want, then they suffer - "I did everything right! What gives?!"
Here's an exaggerated example: one of the common societal rules is to brush your teeth once in the morning and once at night (at least). It may be the case that this does not work for you, or maybe your set of teeth have evolved past the typical human's, and you don't even need to brush your teeth at all.
Point being, if you could achieve your desired results doing less work, less steps, or just done another way that works best for YOU, then do THAT. Vice versa, you may need to work harder or add a couple more steps to your process to achieve your goals.
Learn yourself, learn what works for you.
Learn From the Greats, Then Become One.
You're likely someone who's looking to be the best version of themselves. As such, you likely model your life after the most successful people in the world.
You say, "okay, if Mark Zuckerberg (Facebook founder and CEO) wears the same t-shirt everyday to save brain power, then surely I "should" do that too and it will lead to similar success." Try it, of course, and if it works: great, but if it doesn't: cut it out immediately!
Zucks does that because it works for HIM. He commits himself to what works for him and his mission, I imagine. In your case, it may be that you enjoy the process of choosing an outfit everyday. It feeds your soul. It's necessary for you. It WORKS for YOU.
Overhaul what doesn't work. Replace it with what does work.
Today, I encourage you to pick one area of life that hasn't been working, and try something that might work better instead! Be free from the constrain known as "the right way to do it" and discover the freedom of doing what works for you :)
No more making yourself wrong for waking up at 9am.
