Hi Lexee15!
May our Lord and lady Bless you richly this day.
I do not have the mysteries wholly committed to memory either - what I used to do (and still do sometimes) is recite and meditate on the 10 commandments. One for each bead, all the way around - not only does this help in the traditional respect of the commandments (their literal sense)…but in their spiritual nature as well…and it helps me to keep track while at work, when actually using the rosary is impractical, or driving, or doing any other daily task.
Otherwise what I do as well - is meditate on any glorious, joyful or sorrowful mystery that comes to mind…like the Trinity for instance. Because the #1 purpose of the Rosary, is to bring us closer to God through understanding Him - as completely as we are able, through Our Lady.
Sometimes I find that I actually am meditating on the recommended mysteries - which are NOT set in stone BTW. But really:anything will work - problems (our own or others), praise, resting in His presence, Bible verses, meditations from booklets, literally anything. Offer up what you are doing at the moment to God through the Rosary…it is a tool for us to use to praise, worship, and Glorify God with…in the pursuit of performing His will. Not a magical talisman or something

, It is the sincerity of our hearts that counts…not the ritual performed, or performing it exactly.
Glory to God
Peace
John
