In my opinion, the biggest obstacle that I feel is the temptation to buy, when we see interesting things, for example food, household appliances and others, it will be easy to buy, after buying it is sometimes not used, and from this fact, of course, I will get rid of these bad habits.
I think the examples you've mentioned could be consider "needs" for people in their house, like electric fan, AC, refrigerators and of course food. I think it wouldn't be a problem to use your funds in these and not consider as obstacle. Maybe your habit of spending your money in unnecessary things which is not very useful, that is the problem. Because in my case, whenever I need things on my house to easily operate things like vacuum cleaner of course I would buy it, and I don't think of it as a problem to achieve financial freedom, I rather have useful things in my home than to be called as financially free. Maybe my own obstacle to achieve it, is that I lack of investment for my future, to not worry about money since I have investment. I invest few but due to expenses its not that big, but I don't rush things so it would be better than nothing.
The biggest obstacle is spending money an unnecessary things,buy things in an expensive prices something of #2000 you bought it #10k or #15k buying that because of flexing, flexing will make it hard for achieving financial freedom and poor planing of financial life and unexpected expenses households, food stuffs if you don't have a good financial plan for your life,you will not make you to achieve financial freedom.getting girlfriend that is not in the same place with you, I mean she is not your wife and she is not in your house, but if she is with you in the house it's less expenses, drinking, drinking will make financial freedom difficult,the place you live,the job you do and the salary, am a lecturer and my salary is #10,000 and my expenses is more than #10,000 no way for financial freedom, and lack of good financial plan in the future.
