How do you guys stay busy?

Hey guys, hope you're all doing well! I'm a couple of days deep, but I haven't been really productive the last 3 or so days due to how tired I am. I believe it's more because of my poor sleeping habits catching up to me, but pmo and abstinence from it has definitely played a part. I try not to feel too guilty about it but it does get annoying at times. Also, it's very easy for temptation to arise when I'm not doing much but going on my phone and laptop. So how do you guys combat this? Would love some tips (biblical tips especially). God bless!
