Hello all just want to say id admire all you gym people ive just started going back

My girlfriend goes to another gym has all these plans set up and planning classes ect compared to me who just goes to the gym does the cardio and goes home i do not enjoy the gym while she loves it and has the bug i just see it as a way for me to be able to eat and lose weight and tone up the gym does not excite me and id much rather not go i only go because i want to look better and be healthier i just want to know how?

1 how do you stay motivated i find it so boring?
2 how do you keep things interesting?
3 why cant i get excited to go i find myself doing random tasks to give myself less time at the gym?

Everyone you are all amazing wish i could enjoy the gym as much as you?
