How do you prioritize long-term tasks and goals that you know must be done but are not urgent?

I have not always been successful in doing that and that’s why I’m here. But I have a Succes story that I can share. For a long time I wanted to have a website on creative nonfiction. I set an alarm on my cellphone and promised to do something for that on Thursdays, 9-10 am. After 6 months, I started the website and after 2 years it’s well known and has brought me much more satisfaction than my whole week works!
I hope this helps.

I write them down at the top of my to-do list in my computer or on paper. I see it every time I check what I need to do for the day so I remind myself about it.
