I think that people need money so they can get all the things they need to succeed in their jobs.
Make sure to be capitalizing the beginning of sentences (and always “I”).
Succeed and secede are homophones in this instance.
Their/they’re/there are all different. They’re would be if you were able to put “they are” into the sentence and have it still make sense while “their” is possessive. There denotes a place.
