Assalam alaikum,
The Messenger of Allah, may Allah bless him and grant him peace, was reported to have said,

''He is successful, who has accepted Islam, who has been provided
with sufficient for his wants and been made contented by Allah with
what He has given him''. [Muslim]

These days when people say so and so is very successful, what they mean is he is making a lot of money. By this noble Hadith, we understand who qualifies to be called successful. It is not having car x, house in y and a job z but:-- Islam, Fulfilled needs and possession of a thankful heart. Note this well.
Best Wishes.
