SHC32-5.2 Demonstrate how reflective practice has led to improved ways of working.
VladimirAG [237]
Reflective practice : studying your own experience to improve the way you work.

for example :
- When i work as an accountant for a beverage company for about 3 years now. Believe it or not, i do more works in this past 6 months than i ever did during the previous 2.5 years.

When i first started this job, i basically do everything at once. I always activate 3 or 4 laptops in my desk because i think it will make me more productive. But i was wrong.I made a lot of mistakes and my jobs become unorganized since doing multitasking robbed me from my focus.

After i tried focussing myself to do 1 particular task of the time, my work results became a lot better and i'm able to do more tasks a lot faster

Why does working out make us feel good
Elis [28]

<em>why does working out make us feel good?</em>

<em />

That "feel good" chemical is known as Endorphins. They are released during exercise because of the body goes through extended amounts of stress when exercising. Have you ever heard of the "Runners high"? It's actually a real sensation that you can thank Endorphins for.

Serotonin is also an important chemical that contributes to why exercise feels this way. Have you ever felt depressed after sitting around and doing nothing? Low serotonin is one of the biggest contributors to feeling depressed. Serotonin is in alot of anti-depressant medications. Serotonin is mainly released through exercise.

There could be a reason not relating to chemicals at all. Working out and seeing the results gives us a major confidence boost.
