It depends upon your priorities in life. If fun, enjoyment, and pleasure are top priorities then spend on whatever your whims are.
It is surprising how easily satisfied you can be when you and your pleasures are not your top priorities.
Ecclesiastes 12:13 *¶Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.
14 *For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.
