Alright, meant to respond Thursday but I'm here now. 10 days is a pretty good first streak. Writing for work counts if you believe it adds to the eventual goal you want. You don't have to put away games entirely, instead you can use it as an existing habit that aids in the one you want. For instance, put away the console when you are done. Do not bring the console back out the next day until after you have written at least one sentence. Then the writing starts getting associated with the reward of gaming. It associates with something you crave.
It is common for life to get in the way of habits, which is fine, but there are also ways to mitigate the risk of a derail.
One, have the habit be as early as possible. The sooner it is in the day, the less risk of it being interrupted by something that comes up before hand. This is why building a morning ritual can be super helpful.
Two, be careful about setting daily goals that fluctuate, aren't specific, or too large. The more nebulous a task is, the less likely you will be to perform it. Saying "I will write today" isn't nearly as effective as "I will write 2 sentences at 10 AM". This will help with the consistency over quality aspect of habit craft. Also keep in mind that large goals, though you may be confident due to new found motivation, can actually lead to large backfire as the motivation may not be there the next day, but you'll still have the mental expectation of yourself to meet the goal you met when you were at peak motivation. This is why choosing a consistent task that you know you can do even when you have zero motivation is the best. Pick the largest task that you can do on your worst day. This will be a very small task (hence 1 sentence) but as long as you are consistent, your threshold for the maximum you can do on your worst motivation day will increase. Like working out at the gym, if you keep trying to lift weights so heavy that you are more often than not failing the lift, you wont make progress. Do the maximum that you can do consistently. As you become more consistant you will trust yourself more with doing this, affecting your identity as someone with the habit you want, and leading to more efficient increases in those habits.
Now that you've gotten our first big streak you ready to make a run for another? See how far you can go with lessons learned on this run? Each additional run helps you git gud.
If so, I'll check in on the regular again starting tomorrow 3 PM PST and everyday after that. Great work so far.
