If I sell some etfs and bonds just a couple days after I bought them, will that cause any issues?

So i just started investing on Wednesday. I put a plurality of my money in VOO, with the rest young into VXUS, VIOV, MDY, and SGOV. I was told by a couple people that this was suboptimal, and that I should withdraw from all the ones that aren't VOO and VXUS and put the remaining money either more into VOO or into SPY. But I wanted to know, by doing this only a couple days after I bought those shares, will this cause any issues? Would selling so soon cause any tax difficulties or be against any trade rules or am I good?

A Roman era peasant is found frozen but alive in the Alps, and after they're thawed out, you are given the task of integrating them into modern society. Aside from teaching them a language that isn't Latin or Koine Greek, what is the first thing you are teaching them about the modern world?
