That depends on what kind of investment you're making. There are some people who became millionaires in small investments. The thing is that they just did their part and became workaholic and try to grew what they have invested.
There are also people who invest in small amounts but invest in many things. So all in all even if their investment is small but many it is still big.
Of course it all make sense its just depend on what you do. Don't be a degenerate, and take the principal of other people. It's immoral. Work hard. There is no such things as useless efforts.
All true ,All make sense even how small it is your effort and work will provide and chase the small to bigger amounts. Investments is like any other things if you workout and give it a sense appreciate what you have it will be worth for you .And from what i observe those people who become rich was poor before that who strives hard and work for many thing to make it happen .The rich Ones ? Most of them who grow are the ones who enjoys money without a proper caring small investments or amounts is nothing on them it have no sense at all.
The only difference is the people who uses and see possibilities in every situation.Just watch the national geographic episode of " American Geniuses ". The road to the top is not an easy one( just take aside the little makeup they've made in the episode to make the movie more promising). It will be against all odds and sometimes it might push you to the limits of your abilities. Every small thing counts, even the cell in our body is made up of small atoms. The problem is that some of us want to earn so big in just a small time and that is unlikely to happen ( unless you've won a lottery ). Working hard + working wisely is a very good combination. Always set your goals, bear and try to move on on what's lost. Be professional.
Small investments can serve educational purposes - you can try investing with leverage, altcoins, try fresh casinos, all with small amounts at first to see how it goes before making bigger investments. Your small investments will most likely not yield any significant returns, but they will give you experience that will help you manage your investments in future to minimize risks and maximize profits.
We win some, we lose some. Some days are good and some days are bad. But experience will always be one of the best teacher. What matters is how you've accumulated the experience and turn your weaknesses into power. Even in sports ( you can't outplayed a veteran player that easy), in work ( some companies always requires experienced workers). In investments and businesses? Well you will be more aware in every transactions and your intuition to work and communication will be sharpened that will give you advantage to some.
