HI, i like to skateboard
That is an awesome action sport!  I love the riding and performing tricks aspect to it!
yes, it is awesome, but also very difficult
Yes, it is!  But keep at it because skateboarding will be represented at the Tokyo Olympic Games in 2020!
wow, i better keep up the practice
You should!  The games will run from  24 July to 9 August 2020 in Tokyo.
i do not think i am good enough yet
You should try practicing at the skateparks that have been constructed specifically for use by skateboarders - it might help you get better!
yes i should. i also need to purchase all the correct safety equipment
You will certainly need that!  Especially if you use the half-pipes, quarter pipes, spine transfers, handrails, funboxes, and vert ramps!
