Needing advice on keeping an engine good

Yes this has the 3 mode engine brake so ill typically go down to 6th or 5th when stopping. Since im in a rural area i more often then not have the ability to roll so i can turn or roll thru in 5th. It just messes my head up. If i dont pull on the stick at the right throttle position i get snagged and get mad at myself then have to reset myself. Most of my issue is patience. I wamt to just roll roll roll but i gotta remember to just be pstient with the rpms and gears. When everything aligns it'll all fall together, i just dont like waiting some days. I tried single clutching once but it felt weird so i may hsve to just get used to it. Thanks again
