Some habits of rich people may be imitated and imitated by those who are not yet rich, but not their lifestyle. Affirming themselves as if they were rich doesn't really help if they just hope without trying their best. Everything requires a process and if someone wants to be rich then they must be ready to fight with their comfort zone.
It's a complete and unnecessary waste of the needful resources you have to wish and try to look like the rich when you are not. What's the point? The rich spend money on their lifestyles because they can afford it. If you are not in a position to spend hundreds and thousands of dollars to groom your personality, you shouldn't do it. I don't say that someone shouldn't try to look good, but do it by spending as few resources as possible so that you don't overburden yourself with an unnecessary wish.
Mind you, not looking like the rich doesn't mean one shouldn't look neat and clean and wear at least pleasant attire. You don't need to wear branded stuff to look good. Millions of people worldwide spend very little money on themselves but still look great. You can compromise on quality for as long as you are not in the position to be able to buy and wear the best quality stuff available in the market.
So, it's all about knowing what's right for us in different conditions and life won't look difficult then. Remember, the grass is always greener on the other side of the fence.
