Honestly, I think GAL starts with the little things, making my bed every morning, cooking proper meals even though that meal is for one, maintaining a beautiful home environment. These things I do for me because, really, who cares apart from me that I make my bed, or buy myself flowers, or spend half an hour cooking something only I will enjoy. Self disciple teaches self respect.
Also, everything is better after eating a meal you've just made from scratch at a table you've beautifully set for one.
There are the big things too: going to the gym, fostering friendships, going out for social drinks, planning and then going on bucket list holidays. This forced me to face my fears - being alone, being rejected - and then I crushed them.
At first everything will feel forced. Why make a bed when all you really want to do is get back in it, pull the covers over your head and feel sorry for yourself. Why go out when all you want to do is get in bed, pull the covers over your head and feel sorry for yourself. But eventually it pays off. You will find yourself out dancing at 4 am and wonder why you hadn't done it sooner. You will find yourself skiing down a mountain with a bunch of strangers or walking through a bizarre in Morocco on your own and wonder why you didn't do it sooner.
As Steve said think back to before you met your spouse. Who were you. What did you enjoy. Write it down. You are not the same person you were then, but some of the things you had a passion for you will still have a passion for. Also, think hard about who want to be (and that question stands whether you R or not) and work towards turning yourself into that person.
