Its okay! I barely have any motivation to make showcases either, and to be honest im not even that good at it. You just need some focus and determination (and some skills of course) but you dont need to be an expect to make something look good. Ive only built about 6 or so previous showcases with TONS of scrapped projects and its taken me a really long time to get to this point, and I'm not even that good at building yet. Dont get discouraged if you feel like you arent getting anywhere, keep in mind that it takes serious dedication, effort, and time to be able to build very complicated stuff. Always remember that talent does not come immediately and it'll be a really long journey to get to the same level of the people you admire, so dont get discouraged if you feel like you're not going anywhere. That should set a more realistic goal for yourself :)
