It's difficult! Spending a lot of time on AT definitely helps because it pulls you into discussion, inspires ideas and forces you to think over. Not to mention poring over shopping carts to decide which deck and which book are indispensible right now :-D
Don't force yourself. IMO tarot is supposed to be a healing, relaxing, interesting and inspiring practice, not something on your to-do-list.
Having a dedicated tarot space sounds wonderful, but do you feel you have to "justify" it by using it? Hm, you do so much for others, and tarot is for you. That's reason enough to have that space. Even if you use it only once a week. So what? You did other things. It's better to have one good meaningful reading when you need it than force a routine when there's nothing to read about. I read for myself rarely (I do read a lot for others, though).
My children are older now, when they were young, I remember how difficult it was to dig out some time for myself. That's just the way it is, you're in the busy years of life. Times will change again, and you will have more time, and tarot will still be there.
I found that there is wisdom and insight gained just by living this life. Some 30 years ago, I studied philosophy at university and felt super clever. I read difficult texts and was sure I understood them. But life taught me to understand them, nothing else. I know now that I had to "grow into them". I feel the same about tarot. (Of course, we forget the wisdom of youth on the way, that's a pity).
In a more practical mood: I bought the Inner Child cards when my children were young and let them use this beautiful deck. That made them understand better why I was interested in the cards and spent time with them.
My daughter also invented a little game for the Lenormand deck that we used to play (I play it nowadays with my niece). That made my decks a part also of her life. All my children have positive tarot memories with me even though they never showed any deeper interest.
Do you want to know the rules for the Lenormand game for 2 people?
Each player gets an equal number of cards on their hands. Taking turns, each puts one card down on the table. As long as no animal card appears, both players add to the pile. The player who puts an animal card first (bear, fox, stork...) takes the whole pile, adds it to the cards on his hand, and both continue to play. That's it. The cards shift from one to the other.
The funny thing about this game is that it hardly ever ends.
We spent many happy hours and we each had our "saving animal" who always brought us luck.
