What do you think is the root of your laziness? I'm the same as you, and honestly its probably a mix of just apathy and never really ever needing to develop a work ethic for anything when I was young since I'd always be able to get by without putting in much effort.
I understand you perfectly, my friend. Procastination is the worst enemy you can afford. I know it's easier to say things than to actually get off your ass and do productive things, but try to create a habit as soon as you can, start with small tasks, like something that takes you 3 minutes to do, every day, and slowly start increasing the time and add new tasks. Getting into a habit is gradual and slow, but it is extremely satisfying when you realize that you have reduced laziness.
Lazy is not a real word. There is always a root cause of your actions (and inaction). If you're having trouble doing something consistently, question yourself as to why you're doing it. Is it what you want to do? What will you gain from it? If its something you do want to do, then question yourself as to why you're not doing it. Is it fear?
iktf, extremely lazy myself. I sometimes think if I had more daily sunlight, near my eyes, I'd somehow get better
