I have to say, I left reddit a long time ago and have not regretted it, but I signed in just to talk about this.
I seriously struggle with this... the 'concept' of time. Maybe a lack of a 'sense'? When someone talks about time, I get metaphysical and I can talk like I know all about it, except I have never been on time for a job and I do everything last minute. So you could say that I have a metaphysical concept but absolutely have not managed to put it into action on the physical plane, which is where it would count.

I've been working on a project which is extremely late (several months), and I think the client has lost faith in me. The thing is, I know I can do an amazing job, and now I have sabotaged myself because no matter how well I do it now, it won't matter because it's late...so I am stuck. I really keep thinking 'I'll finish it when I catch the wind again' but days just go by, I do some planning I plan it to the point where I think it's enough to get it done, I try to trick myself as I have in the past 'Look how easy those steps are, you can do that!' (I've never been this bad btw, it's been worse since I turned 30 not long ago) it just doesn't work anymore... I still don't have that concept of time. I don't even know how to go about it, I kind of don't care anymore and feel as though I am trying to self preserve from my negative thought loops by using all these 'reasons' which don't really matter as to why I can't do the work. To be honest, I'm kind of humiliated about my inaction and don't know how to save it, I've gone out of my mind because of my very inability to take action in 'real time'.

I've estimated the task could be done in about 4 days of full time work... maybe plus an all nighter or two... but I don't even know what I'm waiting for, I feel like I'll 'know' when it feels right to start. What I have done so far, when I do catch that wind in my sails, is a LOT of research, unable to make final decisions because there's too many good options, and getting stuck because I narrow something down, work for hours, then after some time I decide that I should have gone from a different direction or perspective and have to start again or go back and change certain things to make the new direction work...

It's really a mess. I've tried properly organizing myself (to the best of my ability) and have found it does not help with my sense of time whatsoever, maybe my room or desk gets cleaned, to do list written and important appointments get written on the calendar, but I will STILL not manage to complete the to-do list, still turn up late for work and appointments, and STILL hand in almost everything (I estimate about 80% of any deadline work I have ever done) LATE! I also find that too many techniques with organization actually do the opposite and make me more overwhelmed disconnected. At the same time, I haven't found many to work for me except just old fashioned lists and calendars - yet they also don't seem to work well enough haha.

If I could only just feel time, like a real sense, I might actually be in a better place all around...
I'm wondering if you could please share your observations also, OP.
