Just Positive words, No negativity.

Change the way you use words on yourself. Always try to use words that empowers and don't downgrade you. For example, Instead of saying 'I made a mistake', just say 'I tried, but I could do better next time', instead of saying 'I was so stupid for doing that', just say 'I won't do that again'.

The fact there is that your psyche will always believe everything you say about yourself. When you say negative things to yourself, your body starts responding negatively, the same as when you start talking positivity into yourself. You are the one to decide how your psyche should operates, whether negatively or positively.

Therefore, you are permitted to only speak positive things about yourself. From now on, stop the act of listening to yourself, and start talking to yourself now. Talk positivity to yourself, and don't listen to the negativity it is telling you.
Stop saying what you are seeing about yourself, start saying what you want to see. Even when you are broke, don't say to yourself that 'I am broke', say I am overly rich.

Life can keep us were we don't want to be, but we shouldn't also speak ourselves into that same condition that life has kept us. Never speak where you are right now, speak where you want to see yourself be.
