Catalyst is a substance which increases the rate of a chemical reaction without getting consumed in the reaction.
Lot of people known as "social media influencers" feel that they are "catalyst" and they can trigger a reaction without getting consumed in it. They tend to overlook that in some cases a reactive by-product causes additional reactions to take place triggering a sequence of events called as "chain reaction".
Be very aware that once you trigger a chain reaction, there is no escaping the snowball effect. Be careful, learn a thing or two and have a wonderful Sunday, on Monday you have to hit the streets.
