The difference between the split ring commutator in a DC motor and the slips rings in an AC generator can be tricky. The split ring makes changes in the rotation every so often. A slip ring just stays in place and is only used as a connector. So a slip ring is for DC, whereas the split ring is used for AC.
I think this should be for your own words but this is what I think you could put in your own words
1. To know that that obstacle will only last so long
2. You have to keep pushing to chase your dreams/goals
3. Take time to focus on yourself and your goals/dreams and how you can achieve it little by little
4. Avoid things that are causing you to doubt the ability to pursue your goal/dream
5. Remind yourself that it’s not always going to be easy but you will get through it
Hope this helps:)
