See title. I'm looking for how this would be expressed in everyday speech, not in news reports (I know 由此可见 but that's too formal). More examples:
The way he walks shows that he is self-confident / From the way he walks, I can tell he is self-confident.
The first time I tried skiing I broke my leg. This shows I'm just not well suited to it.
Your dark tan tells me you like spending time outdoors.
Does the answer involve the word 表示? Thanks in advance.
