We have to come out of our comfort zone to get something big. I don't have enough cash to go for Lump-Sum investment so I prefer to go with 100$ per week (i.e. DCA method). If that money is available to me easily per week then it's fine otherwise I have to look for cuts to manage my investment.
To me financial cuts mean, cutting down spending's on outdoor food (that is good for your health too), luxury items like branded clothes, wrist watches etc. There are spending's in our lives which we all can easily cut down without putting too much stress on our life styles.
There are some certain needs that shouldn't be cut off on somebody's life because of how Important it is and in terms of going out to get some things such as wristwatch or taking the family out for some fun shouldn't be seen as mismanagement of money or leaving a luxurious life because those things are normal and very important for families, so I'm of the opinion that instead you to be investing $100 weekly while you deprive your family from some important basic needs you can actually cut your weekly accumulation amounts abit, let's say in stead of $100 weekly you can bring it down to either $40 or $50 on a weekly and you will see that by cutting it will not prevent you from the amount you wish to achieve in the future.
