Managing your income and expense is something that should be done by everyone and in every season, not just the holidays. It would not matter if you spend some extra on your family, they need you and they depend on you for their expenses if you are the sole bread earner - I dont see anything wrong in that. It is not possible to live alone in this world and be healthy.
But in case your trading or income was not upto the mark, spending a bit less helps to save some for the next year. Life is all about adjusting and compromises, you never get what you actually want but if your needs are like a common man, you will not face troubles.
Right now the holidays are over and the market is on the 41k USD mark. It is a good time to place orders on the bearish side and make the first profitable trades of the year.
Unfortunately it is not as easy as that. Sometimes you just can't say no to your family, money has this balancing issue between couples, if you have very little of it then you are probably either fighting or at the very best you are fine, people could be happy together without money and see this as "their" problem and not blame their spouses.
However when you do have money and you decline to spend it and just save it, unless your spouse is like you then you have a problem. If you tell your wife "honey we can take a 2 day break and go to some nice hotel and relax a bit but we are not going to do it because it is better to save the money", that is not going to be easy thing to make them understand.
I gave that example because that is literally what I am going through right now, I have a bit of money saved aside, and since me and my wife had a pretty rough period, she wanted to leave for a 2 day break, saying no while having the money was impossible so we will probably spend a very high amount for a useless "break".
