I am in the IT industry working with software all day long from logic to code. Sometimes, very seemingly small things take a long time while larger tasks are solved in jiffy.
I have a habit of letting things lingering on: if something is complicated, I'll do it later; if it's not a lot to do, I'll do it later; if there's too much chaos around here I'll do it later.
This procrastination leads to bad consequences, such as late night stays in the office, to the point where it's now almost turned into a habit (something I have observed with several people), which ruins my social life during week days.
It's a major issue, any research or helpful response can save lot of US.
