How do I first punish myself before being at office on time?

Apparently you also hate your job desperately too.

Lateness, unproductivity, passiveness and so on, are signs that you should be doing something differently.

I really love the job I have, it is very satisfactory. But I couldn’t get over my laziness.

Will try that, it goes unsaid. Not the point of my post.

No you don’t. If you did you would be there on time. By the sound of your language you live in an authoritarian culture, or a culture steeped in ancestor reverence. The fact that you said your job is merely “satisfactory” tells me that you do it just for the money and nothing else.

Alright, I wasn’t trying to be sarcastic or anything. I may be missing your point. I have never heard of a person punishing themselves. Seems to me life is hard enough as it is. Why not turn the punishment you are already going through into a reward by breaking the habit of being late? If I’m off base again, then I appologize.

Hah very funny, go be a pervert somewhere else

You either have very poor time management skills or lack of organisation skills in the morning. I’m assuming you are a male, so finding what to wear in the morning will not be one of the reasons you are late. Either you are self employed or your boss is pretty relaxed about you being 45 minutes late for work. Why not try for one week to wake up one hour earlier and push yourself to get out of the door at a certain time. If you are still running late, than punish yourself by not allowing yourself to buy lunch for that week or better still, stay back after work. The more you stay back trying to make up for your tardiness, the sooner you realise that staying back is not ideal and you are not going to see your family earlier and also, you end up missing out on social after work get-together.

You won’t need to punish yourself if you continue to be late - your sudden lack of employment will be punishment enough.
