It is time to get hard on yourself. Change your "to-do list" to a "must do list". Make posting on social media, writing, reading, making your bed, flossing your teeth a must. Make those things a red-hot priority. Not a list you where you can change "Monday" to "Tuesday".
Give your self a "Not to-do list". Stop doing the things you know hold you back. Or use this list as the opposite of the Must Do List. Saying I must post on Instagram is the same as saying I must not not post on instagram.
Start journalling. Develop a set of questions to ask yourself everyday, every week, and once a month.
Where do you want to go? Why?
What did you accomplish this week towards getting there?
What did you mess up? What did you learn?
What situation might (or did) trip you up or stress you today/this week?
What do you need to do this coming week?
What tools or skills do you need to do it?
What situation either inspired you or stressed you today? Why?
Keep trying, keep posting, keep writing, keep reading, keep sharing because you do not know what will hit and what will miss. Every time you share something you created you get better at creating and sharing. You can always ask for help and we all need to take breaks but those breaks can't stop us.
