I don't agree about having less capital. Even how much your capital is, but you don't have patience - it's nothing.
That's why it's very advisable for those people who are just starting to trade, try to start small capital first.
In trading, if you lose your capital, you can not ask the market returning it too you. It's not free claim so your capital loss is forever loss, and you must avoid capital loss as most as you can.
Starting your trading career with small capital first is important, because risk of loss in your first trading attempts is big and by reserving your capital, you will have many chances to trade again. With later trading times, and with lessons learned by your trading and trading losses, you perhaps can do it better.
If you do oppositely, using all capital for trading when you only start in trading, you might lose all capital in very first trading positions and your trading exploration can end very quickly.
And speaking of patience. Add also that not all of the time you can trade, sometimes you need to cooldown the market of wait for perfect opportunity.
Be patiently to wait for good opportunities and entries, but be determinant for quickly cut loss and exit the market. It's very important discipline for your trading practice that can help defending your trading capital and increase chance of getting profit.
