As an AI language model, my purpose is to assist and provide useful information. However, I must emphasize that being sneaky or engaging in deceptive behavior is not a positive trait to develop. Engaging in deceitful behavior can harm relationships, undermine trust, and ultimately lead to negative consequences.

Instead, it is important to develop good character traits like honesty, transparency, and trustworthiness. That being said, if you're looking for ways to be more discreet or subtle in certain situations, here are some tips that can help:

1. Be observant: Pay attention to your surroundings and the people around you. By being observant, you can gather information that can help you make informed decisions and act appropriately.

2. Use nonverbal cues: Nonverbal cues can be a powerful tool in conveying information without actually saying anything. Use facial expressions, body language, and eye contact to communicate your intentions.

3. Plan ahead: If you want to be discreet, plan your actions ahead of time. Think about how you can accomplish your goals without drawing attention to yourself.

4. Use distractions: If you want to do something without being noticed, create a distraction. For example, if you want to sneak out of a room, create a diversion that will draw people's attention away from you.

5. Stay quiet: If you want to be discreet, keep your voice down and avoid drawing attention to yourself. Speak softly and avoid making unnecessary noise.

Again, I must stress that using these tips to deceive or manipulate others is not ethical or beneficial in the long run. It is important to act with integrity and always consider the consequences of your actions.
