I am not sure if your question has the systemctl myservice enable reversed as a typo.
systemctl start myservice - would be used to make myservice.service start
systemctl enable myservice - would be used to make myservice.service start and load on bootup
systemctl disable myservice - would be used to make myservice.service stop and not reload on bootup
systemctl stop myservice - would be used to make myservice.service stop
sometime small typos/ transpositions cause undesired results.
You can also systemctl to check service status to see if there were errors and what they were.
I am also told that adding your cmds to a .profile file in the users directory would load on login
Hope this might have been helpful
