The thing is that I haven't time to procrastinate (jejhehe)...

"Don't have time" is more common, but "haven't time" is fine.

I think that the reason (for that/why) is that I have tried to keep myself motivation abouted to work, thinkingelling myself that this is a very important activity, imagining the benefits in the future that could come if... (I just do this or that).

"Have tried": this describes something continuing to the present, so the present perfect should be used.

"Telling myself": Especially without the comma, "thinking" suggests to me that you are referring to your motivation for trying to stay motivated. "By thinking" would make it clearer, but it isn't as idiomatic: "by thinking" is a phrase that I associate with thought processes, such as "Solve this problem by thinking about the cases where n is 1, 2, and 3 first."

But, some tips that can servebe helpful are:

- DoMake and follow an agenda (in my case the gfor me, Google cCalendar is very useful).

I'm guessing that you might have had the verb "hacer" in mind. "Make" is a better translation when it involves creating something, rather than carrying out an action.

I use them to remember some task urgent or activitietasks in a list.

"Activities" by itself sounds strange. "Activities that have been planned" might be better. If you are just using "activities" to refer to things that need to be done, you should remove it or write "other things that need to be done." Otherwise, it sounds redundant when you have already written "urgent tasks."

- Triey to follow routines.

Be strict with the hoursone's schedule, establish goals, follow some activiroutines like the showering, dressing or eating breakfast before work and after that go to a space of working.

"Some activities like" introduces an expectation of parallel structure, so the gerund should be used for all three items in the list.

"After that go to the office/one's workspace" is unnecessary when it's already implied by "before work."

- Prepare the work environment for the work.

Use a specific place for that and putmake it nice.

I hope thisese tips would bare useful for you!

Or possibly: "will be useful"

I capitalize Google Calendar because it is a brand (proper noun)

I use them to remember some task urgent tasks or activities in a list.

I think "a list of activities" would sound more natural here. This is also called a to-do list

- Triey to follow routines.

Be strict with the hours, establish goals, follow some activities like the shower, dressing oring, getting dressed or eating breakfast before work and after that go to a workspace of working.

"The shower" brings to mind the physical location rather than the activity. Since you are describing activities here, I changed them all to -ing verbs. In general, comma separated lists like this should have similar structures (notice how be strict, establish, and follow are all commands)

The sentence is still a little unnatural though and I would suggest breaking it into two. I'm interested to see what other users suggest but would be happy to talk with you more about this if you'd like.

- Prepare the environment for the work.

This now indicates work as a verb

Use a specific place for that and putmake it nice.
