Correction:

I (always use capital I) hate the holidays. (Full stop for a new topic) I only want to sleep most of the time. Others (Plural - more than one person - use 's') know that I'm active! That's (Capital T for start of new sentence) the truth but I'm (no need for big) lazier during (during is a better word to use - 'during the holidays' - a period of time) the holidays, (comma for breath) so that is why I hate them. (can refer to your holidays as them) I love being (to be = being) a productive person. I planned to work with SASP (?) this week but because the dork driver travelled back to his country from 21st (st not th - used only for 24 and above and no need for 'of') June and he will be back / return (perhaps a word missing) on (specifying what date) the 15th September. I'm (always use capital for I) so excited to start studying at (no need for the) university. Also, I miss all of my friends and I'll (always use capital for I) try to meet them all. By (New sentence - capital letter) the way (no need for exclamation mark) the holidays weren't (weren't instead of wasn't) too bad, at least I had time to learn many (many instead of my?) interesting things.
