This is me. These are the things I know about myself. If you were to design a routine to encourage me to form a new habit, you would probably try to keep everything else around me fairly similar. For instance, if someone likes being in bed early, you would never try to create a new habit of an evening workout, right? It would be out of their way; straining the healthy processes they've already established for no reason. When you look at adding a new habit to your life, you should look to form it around the positive processes about yourself that you already do/like.
I recommend writing a list:
Life strategies I love:
-Waking up early
-Early morning workout
-8 hours of sleep
-Early to bed
-Eating doughnuts when possible
Life strategies that are getting in my way:
-Eating too many doughnuts
-Being too lax on the weekends with my diet
-Not enough focus/direction during morning workouts
-Hit or miss with water intake
Okay. So if this were your list, what would you do? It looks like I have some good habits about my morning routine, but sometimes getting up that early means that those morning workouts can lack direction/focus. What do we do? I would recommend that this person tries to create the habit of writing up the full workout they're going to do the night before as part of a going to bed routine. This would take my eyes off a screen and get me handwriting and thinking about my exciting morning before I go to bed. Now I will wake up with more excitement AND preparation knowing what I have to look forward to.
Again, this is a person who loves to exercise and to be challenged! What a great recommendation for someone like me! What does your list look like? Maybe you like eating a lot but don't like sweating! Maybe you hate the mornings and have a hard time sleeping at night. How about we take one hour AWAY from watching TV/playing online at night and instead now you use that time to go for an hour long walk (take your dogs and/or your kids/spouse/friends!), then a hot shower, a glass of water, and straight to bed with no screen time afterwards. Suddenly you're creating a routine, you're sleeping better, you're engaging with your family/community, and you're getting in movement, likely without breaking a sweat.
The purpose of all of this is to realize that being who you are is not only okay, but it is where you will be the most successful! It is so easy to try to be like that cool fitness model/sports athlete, but do you really want to live that lifestyle? Chances are you just want to be a slightly more developed version of yourself. So start with who you are. Maybe take a little extra time this week to get to know who that is.
Write your list and analyze each item line. Do I like this? Could I do this better? Could I be kinder to myself here? Am I willing to actually change/give this up? What can I expect from engaging with these changes? What makes me happy?
Habits can take 21-254 days to form depending on the difficulty of the task and the compliance of the individual. The average habit formation takes about 66 days and that is with consistent work. Try not to choose too many habits at a time. Step by step. A little love, kindness, and an honest look at who you are and what you like to do will simplify the whole process.
