stay comfy, keep things chill indoors and if the weather's nice, get outside and touch some grass. Of course, don't go too far or off to somewhere you don't know, but even if there's a small local park and the sun is out, a short walk there to vibe and see hexagons in the grass as it shuffles in the breeze is an amazing feeling. If it's not you're thing though, don't worry - you don't want to push yourself and you'll get excellent patterns from any surface inside too.

having a stupid show on during the come up is always a great time - i've never laughed harder than I did at spongebob when i took my first tab when i was like 19 or 20, and it was at the point that we were laughing so hard that I had to take a deep breath that I realised the walls were breathing with me.

don't paralyse yourself with fear or anxiety that you might have a bad time. of course, anecdotes aren't data, but i'm profoundly depressed and have never had a bad time on psychadelics, especially acid. Rather, enjoy the anticipation of the great time you're going to have and how energised you'll probably feel on the way up.
